ATTINY417-MF

Overview

The ATTINY417-MF is an 8-bit AVR microcontroller from the tinyAVR 1-series, featuring a 20 MHz CPU with hardware multiplier. It includes 4 KB of self-programmable Flash memory, 256 bytes of SRAM, and 128 bytes of EEPROM. The device operates within a voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 20 MHz at higher voltages. It is housed in a 24-pin VQFN package (4x4 mm) and provides 22 programmable I/O lines. Key peripherals include a 10-bit ADC, USART, SPI, TWI, TCA/TCB/TCD timers, RTC, and Event System.

Feature Summary

• Supports low-power architecture with multiple sleep modes including Idle, Standby, and Power-Down with full data retention.
• Integrates Core Independent Peripherals such as Event System and SleepWalking for efficient background processing.
• Features accurate analog capabilities including a 10-bit ADC, 8-bit DAC, and multiple internal voltage references.
• Includes Configurable Custom Logic (CCL) with programmable look-up tables for custom logic implementation.

Applications

• Battery-powered consumer electronics requiring low power consumption
• Industrial control systems utilizing core-independent peripherals
• Smart home devices with capacitive touch interface requirements
• Wearable technology applications needing compact packaging

Procurement Notes

Verify the specific suffix 'MF' indicates tray packaging when ordering. Confirm the temperature grade matches application requirements, as the datasheet specifies ranges up to 125°C for certain speed grades. Ensure the voltage supply aligns with the selected operating frequency limits defined in the electrical characteristics section.

Selection Notes

Select this component for designs requiring a balance of processing speed and peripheral richness in a small footprint. Consider the 4 KB Flash limit for code size constraints. Evaluate the need for the Event System if deterministic timing between peripherals is critical. Verify that the 24-pin VQFN package fits the PCB layout constraints.

Part Context

This part belongs to the Microchip tinyAVR 1-series family, which shares architectural similarities with other members like ATtiny817. The 'M' suffix typically denotes the VQFN package type, while 'F' often relates to lead-free or specific environmental compliance attributes common in Microchip's naming convention.

Replacement Considerations

ATtiny817-MF offers identical pinout and features but with 8 KB Flash and 512 B SRAM. ATtiny416-MF provides similar specifications but may differ in specific peripheral counts or package availability. Check datasheets for exact electrical parameter compatibility before substitution.
